Activity Overview
Youth investigate how mirrors can be placed to redirect the path of light to gather data from a distance.
Guiding Question
What is the best way to redirect light to gather data from a distance?
Youth Will Do
- Explore and evaluate the properties of light.
- Determine how to place mirrors to redirect the path of light based on the properties of light.
- Evaluate their system to suggest improvements.
- Develop ideas for changing the design for better ability to redirect light.
- Explain the strengths and weaknesses of their systems based on what they now know about light.
Youth Will Know
- Engineers design technologies that capture data.
- Mirrors can change the direction of light.
